SecAppDev Studio Day

The SecAppDev Studio Day is a unique event where we record selected lectures from the SecAppDev course in a TED-talk style setup. This professional recording environment includes high-quality audio and video capture, and may feature occasional shots of the audience to enhance the viewing experience.

Each lecture will be followed by a Q&A session, providing attendees the opportunity to interact with the speakers, ask questions, and delve deeper into the topics discussed. This format ensures that both the live audience and future viewers can benefit from the expertise shared during the sessions.

Studio Day Lectures

We have selected the following SecAppDev 2026 lectures to be recorded at the Studio Day.

An Updated Security Model of the Web

Deep-dive lecture by Philippe De Ryck

Web security is messy, complicated, and under constant evolution. Often, you even start wondering why certain issues cannot be solved by the browser directly.

In this session, we investigate the security model of the web. We learn how browsers think about security, and how we can leverage that to build more secure applications. We explicitly focus on new browser features and how they can be used. Examples include the sanitization API, new cookie prefixes, as well as features focusing on script integrity. This session will give you an up-to-date understanding of browser security in the modern age.

Philippe is recognized as a Google Developer Expert, acknowledging his contributions to web application and API security. He also organizes SecAppDev, an annual week-long application security course in Belgium.

AI Memory, Mapped

Deep-dive lecture by Natalie Isak

Persistent memory transforms AI systems from stateless tools into context-aware systems, but it also introduces a class of risks. We will cover key risks including continuous exfiltration via prompt injection, delayed tool invocation, and negative psychosocial impacts. The second half focuses on building memory-safe systems by design: threat modeling memory, observability strategies, and runtime safety monitoring at scale (including BinaryShield, a novel privacy-preserving method for sharing textual customer content to detect coordinated spray attacks).

Secure by Design — Ideas and Techniques

Introductory lecture by Dan Bergh Johnsson and Daniel Deogun

Most security vulnerabilities aren't introduced by careless developers. They're made possible by design decisions that nobody flagged as security decisions at the time.

This session introduces Secure by Design as a way of thinking, not a checklist. We'll look at how everyday design choices — how you model your domain, define your types, draw your boundaries — can close down attack surfaces. The same thinking that makes code correct and maintainable tends to make it secure. Security becomes a property that emerges from good design rather than a layer bolted on afterwards.

AI Head, Omegapoint

Dan Bergh Johnsson works at the intersection of software architecture, security, and large-scale system design. He has decades of experience designing and reviewing complex systems where security, stability, and delivery speed are in constant tension. Dan is co-author of Secure by Design (Manning) and a frequent international conference speaker. His talks focus on how architectural and design choices — increasingly involving AI — shape long-term security, system behavior, and organizational responsibility. He is particularly interested in what gets lost when productivity increases faster than system understanding.

SBOMs and their Role in Security

Deep-dive lecture by Alexios Zavras

A practical deep dive into Software Bills of Materials (SBOMs): what they are, what they are not, and how they fit into modern software security. We will cover common data models and formats, how SBOMs are produced and consumed, and how they enable better visibility and faster decision-making across the software lifecycle. Interactive participation is particularly encouraged.
